PINOKY is a wireless ring-like device that can be externally attached to any plush toy as an accessory that animates the toy, such as by moving its limbs. A user is thus able to instantly convert any plush toy into a soft robot. The user can control the toy remotely or input the movement desired by moving the plush toy and having the data recorded and played back. Unlike other methods for animating plush toys, PINOKY is non-intrusive, so alterations to the toy are not required. In a user study, 1) the roles of plush toys in the participants’ daily lives were examined, 2) how the participants played with plush toys without PINOKY was observed, 3) how they played with plush toys with the device was observed and their reactions to the device were surveyed. On the basis of the results, potential applications were conceptualized to illustrate the utility of PINOKY.
